MEASURE
Measure Mode
Determines what kind of measurements the spectrum analyzer makes: signal analysis, stimulus
response, or signal normalization.
Syntax

Option Required: Option 010 or 011.
Related Commands: Commands affecting amplitude, such as
AUNITS,
DL, INZ, LN, MKA,
MKREAD, MKRL, RL, RLPOS, ROFFSET, TH.
Preset State: MEASURE SA.
Example
Activate the tracking-generator source output.
OUTPUT
718;"MEASURE
SR;"
Sets spectrum
anul~z43r
to stimulus-response
mode.
OUTPUT
718;"SRCPWR
-1ODM;"
Makes the tracking generator source power the active
function.
Description
“MEASURE SA;” activates spectrum analysis and auto couples the spectrum analyzer
functions. If AMB ON or AMBPL ON and RLPOS have been executed prior to MEASURE SA,
MEASURE SA turns off the reference level position. When normalization is off, all amplitude
units are specified in absolute values determined by:
n
Amplitude units (AUNITS).
n
Reference level (RL).
n
Reference-level offset (ROFFSET).
n
Input impedance (INZ).
n
Logarithm scale (LG).
n
Linear scale (LN).
w
Amplitude Correction (AMPCOR).
“MEASURE SR;” activates stimulus-response measurements and uncouples the sweep time
for faster sweep times. If AMB ON or AMBPL ON and RLPOS are executed, MEASURE SR
activates the reference level position. When normalization is used, amplitude units are
specified relative to the display level.
